i can get v0.1 working again, by installing the ciso249 v5 through wad manager, this appears to over write the ciso that comes with the new loader.
I don't know if this is the correct thing to do , but it works for me.
The problem is, if i want to go back to the v0.3 loader i have to install the ciso for that, this in turn stops v0.1 from working.
Would be ideal if there was a ciso that was compatible for both.
